摘要： A SIMD processor responds to a single min/max instruction to find the minimum or maximum valued data unit in an array of data units. The determined minimum/maximum value and an associated index value thereto may be output. Alternatively, the value of a data unit in another array may be output at a corresponding location. A further single instruction executable by the SIMD processor, may be applied to results obtained using such a single min/max instruction, to allow such instructions to operate on two dimensional arrays.

摘要： An apparatus for processing variable length coded data includes a coefficient buffer unit and several lookup tables. The coefficient buffer unit includes a coefficient memory and an index register for storing an indication of a non-zero nature of coefficients stored in the coefficient memory. Advantageously, the lookup tables may be altered to adapt the apparatus for processing variable length coded data to handle encoding or decoding video adhering to a specific standard. Furthermore, the lookup tables may be adapted to accelerate the determination of the presence of escape codes and the subsequent handling of the escape codes.

摘要： Methods and apparatus for improving the quality of images generated by reduced resolution video decoders and new and improved video decoders which produce reduced resolution images are described. Methods and apparatus for identifying conditions within an image which may significantly degrade image quality if particular portions of the image are used by a reduced resolution decoder as reference data are described. One specific embodiment is directed to a new video decoder which decodes portions of a single image, e.g., frame, at different resolutions. Areas of the image along high contrast vertical or horizontal edges are decoded at full resolution while other portions of the same image are decoded at reduced resolution. By decoding and storing portions of reduced resolution images at full resolution for reference purposes, the risk of prediction errors resulting from the use of downsampling on reference frames is reduced.

摘要： Methods and apparatus for implementing single instruction multiple data (SIMD) signal processing operations are described. The apparatus of the present invention include new registers and register arrays which allow data to be accessed at a word as well as sub-word or sub-register level. The registers and register arrays of the present invention may be used when implementing a system based on a SIMD architecture. Registers implemented in accordance with the present invention include a plurality of pass gates that allow an entire n-bit word stored in the register to be accessed and output as a single word or for a sub-word portion of a stored word to be accessed and output. During standard operation the registers are accessed on a word basis. However, during column access operations, e.g., when performing a transpose operation, access is performed on a sub-word basis. The ability to access the registers of the present invention on a word or sub-word level make implementing transpose and various other row/column data manipulation operations possible in a relatively straightforward manner without data buffering. In addition to the novel registers and register arrays of the present invention, various aspects of the present invention are directed to new and novel SIMD instructions, e.g., SIMD move, add, and move instructions, which support the specification of data to be processed as operands which identify rows or columns of register arrays as opposed to merely identifying registers as done with conventional commands. A transpose command is also supported.

摘要： Methods and apparatus for implementing video decoders at a reduced cost are described. The methods include data reduction techniques, simplified inverse quantization techniques, and dynamically varying the complexity of image enhancement operations, e.g., prediction filtering operations, as a function of whether luminance or chrominance data is being processed. In order to reduce data storage requirements, luminance and chrominance data corresponding to previously encoded images may be stored at different resolutions with, in some embodiments, chrominance data being stored at less than half the resolution of luminance data. In various embodiments, data representing portions of B frames which will not be displayed is identified and discarded, e.g., without performing a decoding operation thereon. Portions of I and P frames which will not be displayed are identified and decoded at a reduced resolution and/or using simplified inverse quantization techniques. The decoded I and P frame data is stored for use when making subsequent predictions if required. Another data reduction technique involves applying different amounts of data reduction, e.g., downsampling, to different image portions with no or little downsampling being performed on image portions located at or nearest to the image's center of interest as determined from information included in a received encoded bitstream.

摘要： An audio processing device may estimate noise effects at a particular location based on noise measurement data corresponding to one or more noise sources. The audio processing device may modify one or more output audio content transmitted by the audio processing device to that particular location such that the modification may cancel the estimated noise effects at the particular location, at time when the output audio streams are received at that location. The noise effects estimation may also be based on audio reception measurement data at the particular location. The noise measurement data and/or the audio reception measurement data may be generated by audio capturing devices placed at or near noise sources, and/or at or near the particular location, respectively. The noise measurement data and/or the audio reception measurement data may be communicated to the audio processing device using wired and/or wireless connections.

摘要： Apparatus and methods for storing data in a block to provide improved accessibility of the stored data in two or more dimensions. The data is loaded into memory macros constituting a row of the block such that sequential values in the data are loaded into sequential memory macros. The data loaded in the row is circularly shifted a predetermined number of columns relative to the preceding row. The circularly shifted row of data is stored, and the process is repeated until a predetermined number of rows of data are stored. A two dimensional (2D) data block is thereby formed. Each memory macro is a predetermined number of bits wide and each column is one memory macro wide.

摘要： A video processing system may receive a current raw video frame and may estimate motion between the current frame and a previous frame to determine motion vectors (mv). Based on the same mvs, motion compensated (MC) noise reduction may be performed and MC frame rate conversion (FRC) may generate a new frame. The previous frame may be noise reduced and/or a raw video frame. A MC frame may be generated based on the previous video frame and the mvs. Noise reduction may comprise blending the current raw frame with the MC frame. A blending factor may be determined based on similarity between pixels of the current video frame and MC pixels of the previous frame. The mvs may be scaled for FRC. Noise reduction may be performed in parallel and/or prior to the FRC depending on whether raw or noise reduced frames are utilized.
